What you save

A page is about 600 tokens in and 60 out, a support reply 200 in and 300 out, an email 150 in and 250 out. Nothing else is counted: no cache discount, no batch rate, no free tier.

How we count

Prices are per million tokens. The big number on each row is blended 3 in : 1 out, the way most work uses a model. A price below Upstage's own is listed as cheapest only when the provider says why.

Credits
Priced in credits or points that convert to dollars, so the rate moves when the conversion does.
Same as maker
Sold by someone else at the price the maker charges.
Not ranked
Below the maker's price on a closed model with nothing to account for it, or from a catalog we could not read reliably. Listed, and never a pick.

Similar models
